Lincoln Electric at AM Strategies Conference: Turning Talk Into Industrial Reality

Key Takeaways

• Lincoln integrated WAAM with welding, robotics, and finishing in‑house.
• Acquired Baker Industries in 2018 to close post‑processing loop.
• Large‑scale 3D printing cuts lead time and waste for infrastructure parts.
• Targeted use cases deliver clear cost, speed, and performance gains.

Pulse Analysis

Additive manufacturing has long promised faster, lighter parts, yet many firms remain stuck in pilot phases due to fragmented processes and costly post‑processing. Lincoln Electric, a century‑old welding giant, leverages its deep metal‑joining heritage to overcome these barriers. By embedding wire‑arc additive manufacturing within its existing welding and automation portfolio, the company creates a seamless pipeline that eliminates the hand‑offs that typically stall scale‑up. This vertical integration mirrors broader Industry 4.0 trends, where digital design, robotic deposition, and automated finishing converge to deliver consistent, high‑quality output.

The technical heart of Lincoln’s strategy is WAAM, which uses wire feedstock and an electric arc to build large metal components layer by layer. Compared with powder‑bed systems, WAAM offers superior material efficiency, especially for high‑value alloys, and reduces waste by up to 70 %. Coupled with in‑house machining from the Baker Industries acquisition, Lincoln can print, machine, and certify parts in a single, controlled environment. The result is a dramatic reduction in lead times—often from months to weeks—and a cost structure that competes with traditional casting or forging, making large‑scale 3D printing viable for critical infrastructure repairs and heavy‑industry components.

The market implications are significant. Utilities, mining, and aerospace firms now have a reliable supplier that can deliver custom, high‑strength parts on demand, mitigating downtime and inventory costs. Moreover, the integration qualifies for the permanent R&D tax credit, allowing companies to offset a portion of development expenses tied to design, testing, and software integration. As standards evolve and workforce skills catch up, Lincoln’s model sets a benchmark for how legacy manufacturers can transform additive technology from a buzzword into a core profit engine.
